After analyzing the structure of Qtopia Phone Library,the scheme to add VoFi Phone modular while keeping the original structure of Qtopia Phone Library is introduced,and then the implementation of the modular is illustrated in detail using a top-down sequence.

Design and implementation of cutting tool path system based on Neutral Message Language and Qt library;

Then the mechanism of Qt library to support scripts like Arabic,which is written from right to left,is.

This paper introduces two algorithms on a minimum path cover problem in QT-graph(the abbreviation of quasi-threshold graph) G which has m edges and n vertices.

This thesis mainly analyzes the problem on QT-graphs.

In the first chapter, we construct a QT-tree on the QT-graph as its tree representation.
